The finger clamp has become a fundamental instrument in the laboratory. It is useful, practical and provides safety in gripping objects during conducting experiments or research work. It provides comfort and ease in handling, avoiding accidents.
Fingered pincer and its evolution in history
As for where they were made and used for the first time the three-fingered pincer is unknown. It is achieved in ancient times that in Egypt this object was already known because they appear in the drawings of craftsmen of that moment. In illustrations where they made reverence to the god of fire, with iron tongs that held hot metals to be molded. In Europe the clamp has been known since 2000 BC. Since its inception it has had the function of grasping hot objects or holding objects to be heated.
It has been used by man in the arts, medicine, etc. In the gripper is currently achieved in the kitchen, to grab food that is fried at elevated temperatures. For transfer very cold substances such as ice. In the washing of clothes to lay in the sun. As a clip to hold the hair. The industry does not escape in the use of the clamp for fastening and cutting wires, pipes. For the scientific field in the gripping containers of substances or mixtures.
What is the finger clamp?
It is a laboratory instrument that integrate the metal materials. It is widely used in laboratories to grab glass instruments that were part of the assembly of an apparatus that was used for the study of a sample. Such as determining the melting or boiling point. They have a simple, simple appearance and with ease of manipulation. It can be adapted to the thickness of the object to be held.
A finger clamp is a type of hand-held tool that is used to grip and hold small objects or materials. The clamp typically consists of two opposing arms that are joined by a pivot, and a mechanism that allows the arms to be tightened around the object being held. The arms are typically covered with a rubber or plastic material to prevent damage to the object being held.
Finger clamps are commonly used in a wide range of applications, including jewelry making, hobby and craft work, electronics repair, and medical procedures. They are an essential tool for tasks that require a precise and secure grip, and can be used to hold objects such as beads, wires, circuit boards, and other small parts.
There are many different types of finger clamps available, with variations in size, material, and design to suit specific needs. Some finger clamps are adjustable, allowing the user to control the amount of pressure applied to the object being held, while others have a fixed grip strength. There are also finger clamps that are designed for specific applications, such as those used in jewelry making or electronics repair.
Features of the finger clamp
It is made up of three fingers, two arms in one has two at its end and the other has a finger with medium height. It is a piece with a lot of mobility, because it can open 180° and rotate to the desired angle. The types that are without a nut, constituted by a cylindrical metal rod that is connects to a universal bracket. Attached to the two arms where the fingers are integrated. Another with nut which is a screw glued to the metal rod, which is adjustable. With two arms in one it contains two fingers and the other one finger.
The material from which it is made can be diverse, there are chrome-plated, cast iron, nickel-plated, plastic, aluminum alloy, steel, wood, porcelain. The clamping fingers are plastic coated. vinyl, PCV for the protection of the objects it will hold. They are considered with an accessory instrument because it is complemented by the universal bracket. From time to time the coating of the gripping fingers can be replaced.
Finger clamp for what it is good for
They are mainly used to hold objects that can change sites without any protection. For the realization of assembly of a apparatus that will serve for an experiment, where instruments such as test tubes, burettes. They can be placed in large or small assemblies without any problems of bad grip. It fits easily and quickly. They commonly hold beakers. Pipettes and burettes.
Finger tweezer function
The tweezers are used to cut, grab or compress objects containing substances or mixtures to be studied. Which are subjected to heat. Be made to allow a better grip due to its shape.
Care for the three-fingered pincer
Are those that the experimenter or manipulator of the instrument must have for the preservation of the material used in the practical. For the successful completion of the study with excellent results. The maintenance of the appliance for its durability. Store well clean and dry in a suitable place to avoid oxidation. Carry out the periodic review in the nuts to prevent malfunction. It is important to search for information about the material to be used in a laboratory practice. Why it prevents the misuse of the clamp, the breaking of glass containers.
Classification of the three-finger caliper
Currently on the market there are several models of caliper three fingers, with a difference in their function. Which are classified into four: Type A, they have a high extension to open their arms. Type B, with lower extension of amplitude in his arms. His fingers are made of cork, resistant but they cannot be replaced. The type C, has no fingers, has two semicircles with an angle of 25°. Allows the gripping of objects, bodies or instruments of size, small diameter. As well there are some that have names like:
Burette clamps are used to clamp burettes during the application of the volumetric titration method. The Mohr clamp: Instrument used for the obstruction of the passage of liquids, contained inside a plastic hose. Of Hoftman, used to calibrate the fluid of a liquid, by means of the pressure of a latex tube. The wooden ones, allows the clamping of the test tubes hot or that will be supplied with heat. Walnut clamp, connects to the universal bracket and serves as a bra. Of hose, it serves to regulate the liquid or gas fluid.
The pressure clamp, exerts pressure on the objects that hold. Coolant or finger clamp, used to hold the object that make up the assembly. Desertion, it serves to clean the wounds in patients. Holder, instrument with two nuts one that fits a universal bracket while the other fits the finger clamp. Made of Nickel non-ferrous. The porcelain clamp, holds porcelain capsules. Plastic, useful for having low heat conductivity, it prevents burns.
For crucibles, they have the form of pliers to hold corrosive and hot objects avoiding contact with the body. Fischer tweezers, used for clamping burettes, with double clamping for two instruments and keep them straight without bending or curving.
